In a matter of minutes my question had been retweeted several times and I’d gotten more than a dozen tips (from writers, editors, and other publishing professionals) which you’ll find below. This served as a great demonstration of how one's Twitter community can be useful. I suggest you follow each of the wise tweeps who replied to me—and follow their advice as well.

@HeatherMcCorkle: Twitter tip: Never write anything you don’t want to read on the front page of the newspaper. Could hurt your career later!

Alice, great post! Twitter is such a fantastic tool! My tip @HilaryWagner1 Don't be a stranger! If you forget about others, they will forget about you! Ask people how they're doing and answer their tweets. :)
